A new species of plant-eating dinosaur with tiny, one-inch-long jaws has come to light in South African rocks dating to the early dinosaur era, some 200 million years ago. Researchers have identified a species of puny dinosaur so odd looking - quills like a porcupine, a parrot-like beak and fangs like a vampire - it probably deserved a small part in "Jurassic Park."Picture: AFP PHOTO / UNIVERSITY OF CHICAGO/TYLER KEILLOR
